Honeywell 30754975-503 Servo-Plate

The Honeywell 30754975-503 Servo-Plate is a critical mechanical assembly engineered for high-precision data logging in industrial environments. Specifically designed as a replacement pen motor or servo plate assembly, this component is compatible with the Honeywell DR4500 Truline 12-inch circular chart recorder series. Whether you are maintaining a 1-pen or 2-pen configuration, this servo plate assembly ensures the motorized pen arms maintain strict positional accuracy for continuous process monitoring. Built with robust materials to withstand the thermal and mechanical stresses of 24/7 plant operations, the 30754975-503 facilitates smooth pen movement across circular chart recorder paper, preventing data jitter and ensuring legible, audit-ready records. This genuine OEM part is the standard for contractors tasked with restoring the mechanical integrity of DR45AT and Truline recorder models.

• Direct OEM Compatibility: Engineered specifically for the Honeywell DR4500 Truline series, ensuring perfect fitment and electrical alignment without field modifications.
• Enhanced Precision: Replaces worn or sluggish pen motor assemblies to eliminate recording lag and improve the resolution of process data trends.
• Industrial-Grade Durability: Constructed to perform under demanding industrial conditions, maintaining calibration in high-duty cycle applications.
• Dual-Pen Support: Versatile design functions effectively in both single and dual-pen recorder setups for comprehensive data acquisition.

Is the 30754975-503 compatible with the DR4300 series?
No, this specific servo-plate is designed for the 12-inch DR4500 Truline circular chart recorder. For the DR4300, a different motor kit is typically required.

Does this assembly include the pen arm?
This is the servo plate and pen motor assembly. While it provides the driving force for the recording mechanism, the physical pen arms and chart hubs are often sold as separate kits depending on the specific recorder configuration.

How do I know if the servo-plate needs replacement?
Technicians should look for erratic pen movement, "hunting" for position, or a complete failure of the pen to respond to input signal changes, which often indicates a failed servo motor or mechanical binding within the plate assembly.
